public_fields

Makes both the struct itself and all its fields publicly accessible.

To expose a struct and its fields outside the current module:

1. Annotate the struct definition with pub
2. Explicitly mark each field with pub modifier

This allows external code to:

• Construct instances directly using struct literal syntax
• Read/modify individual fields without accessor methods

Example

pub struct Foo {
   a: i32,
   b: i32, 
}

// External code can:
let foo = Foo { a: 2, b: 10 };
assert_eq!(foo.a, 2);
assert_eq!(foo.b, 10);

Note

Struct visibility also depends on parent module's visibility1,4. The containing module must be public to allow cross-module access.

For crate-internal visibility, consider pub(crate) instead1,2.
